The present invention relates to apparatus for handling coiled material, and in particular involves the provision of mechanism for securing successively the elevation, from a reeling device, of each coil that is formed thereon, and the sidewise transfer of each coil so elevated to a conveyor or the like, whereby the reeling device is rendered immediately available for theformation of another coil.

The invention resides in the combination l and arrangement of parts hereinafter set forth in detail, reference being had to the accompanying drawings, in which- Fig. 1 is a view, partly in section and partly in side elevation of the mechanism embodying my invention, as applied to a reeling or coil-forming device of well-known construction.

Fig. 2 is a fragmentary view illustrating the parts in positions that they take for the elevation of the completed coil. V .y

Fig. 3 is a view similar to Fig. 2, illustrating the parts in the positions that they take for the lateral delivery movement of the elevated coil.

` Like reference characters refer to like parts in the diierent figures.

Referring first to Fig. 1, the coiling device or reel is suitably disposed within a cylindrical casing or shell 1, the latter being supported in any desired way, as by a hollow ystandard or base preferably made in two parts, namely an upper part 2 and a lower part 3. The upper part 2 provides a central internal sleeve 4, which sleeve, as here shown, has a circular enlargement 5 at its upper end, for the rotative support of the reel or ceiling device proper.

Said reel or ceiling device as here shown consists of a circular plate 6 disposed within the casing or shell 1 and having two circular series of upstanding guide lingers 7, 7 for the confinement of the convolutions of the coil.

' Secured to the plate 6 is a bevel gear 8 whose hub finds bearing on the circular enlargement 5 of the sleeve 4; a driving bevel gear 9 meshes with the gear 8, said bevel gear 9 being secured to the end of a suitably journalled driving shaft 10 that is rotated, during yeach reeling or coil-forming operation from any suitable source of power, thereby to revolve the reel at such a speed as will form the moving material (hot wire, rods, or other stock) as delivered to said reel into a coil, with the successive convolutions confined between the sets of lingers 7, 7.

Each such coil thus laid or formed by directing the moving material into the revolving reel, finds its bottom support on a plate 11 which overlies the plate 6 and which is apertured for the passage of the guide fingers 7, 7 therethrough. Said plate 11 is supported independently of the plate 6, being carried by a member 12 which is 'secured to the upper end of a rod 13, the latter being slidable in the bore of the sleeve 4. The member 12, in the normal coil-receiving position of plate 11'as shown in Fi 1, rests upon the center of theplate 6, an during formation of the coil, thel entire structurewithin the shell 1 A is rotated by the driving shaft 10. Upon completion of the coil-forming or laying operation, the rotation of shaft 10 is discontinued, and thereupon is inaugurated the 0peration of certain mechanism, now to be described, for elevating the completed coil above the guiding fingers 7, 7, and for then shifting said coil laterally away from the reel, so as to make room for the immediate resumption of the ceiling operation on the next piece of stock.

Still referring to Fig. indicates a worm carried by a driving shaft 15, which shaft, u on discontinuance of the rotation of sha 10, is caused in any suitable manner to rotate so as to carry the coil lifting and shifting mechanism through a complete cycle of operations, and then to bring said mechanism to rest in its starting position. The worm 14 meshes with a worm gear 16 on a shaft 17, and the latter carries a gear 18 in mesh with a larger gear 19 on a shaft 20,- the relation of the vgearing being such that two complete revolutions of the shaft '17 are required for a sin 1e revolution of the shaft 20. The shafty 1 carries two crank arms 21 and 22 which are nearly 180 apart, and the shaft 2O carries two crank 1, the numeral 14 i esA . supporting standard of the reel. Pro3ect1n'g.

The long arm 39 of this bell `cranklever extends upwardly and at its freeend makes a pivotal is supported, injuxtaposition to the reel, by

means of al track 41 extending horizontally' above said reel. A roller 42 on the end of 41 therebat the proper time to 'act upon the completed' and elevated coil with a'pusher bar 43, carried by the ends' of said 'member 40. The operation ofthe mechanism is as follows ing shaft 10 is discontinued'and, simultane- Assume the parts to be inthe positions illustrated by F1g.,1 when, upon the completion .of the coil in the reel, the rotation of drivously therotation of driving shaft 15 .is inaugurated, At the very outset 'of said lastnamed rotation, the crank arm-21 movin clockwise andthe crank arm 23 movinganti'- o clockwise, these arms nevertheless travelin the same eneral direction, viz, to the right in- Fig. 1v an as a consequence of their combined movement. through nearly one full revolution of shaft 17, and nearly a half revolution of shaft 20, as shownin Fig'. 2, they pull the member 27, through links 25 and 26, well'to the right; this causes a clockwise angular movement of the bell crank 28, 30 on its fulcrum 29, which thrusts the cross head 32'v upwardly and, through the action of rods 33 and 13, raises the plate 11 far enough so that the completed coil isclear of the fingers 7,7.

Durin this first nearly complete revolution of t e shaft 17, the crank arms 22 and 24 (unlike the crank arms21 and 23) have been neutralizing each otherseect on the membe'r 36 with the result that no app-reciable displacement inthe position of said member 36 is effected in this rst part of the cycle of operations, although the links 34 and 35 are carried from the positions shown in Fig. 1 into the positions shown in Fig. 2.

However, as the rotation of shafts 17 and 20 continues, from the-position illustrated in Fig. 2, this inactivity of the member 36 (except to' swing idl on its pivotalconnection with arm 37) no nger revails; on 'the contrary said member 36, uringthe next por-v tion' of the frotation. is y .drawn bodily to the left bythe links 34 and 35, causing the arm' fact that the member 27 lby the neutralizing action of links 25 and 26, is not at this timemoved bodily, butfonly swings idly-onl its point of pivotal connection with the bell crank arm 28.v

The balance of the .cycle operations, to

complete two full revolutions of shaft 17 and one full revolution of shaft 20 is operative to shift both members 27 and 36 bodily, the member 27 through. the'thrust of links 25 and 26 moving to the left from the position of Fig. 3 'to the 'position of Fig. 1 and thereby de-. Y pressing rod 33 so that plate 11` will resume its member 40, is adapted to travel on said track of operations and leaves the reel free for the formation of another coil, whereupon the rotation ofthe shaft 15 is again' inaugurated, toimpa'rt two complete revolutions to the shaft 17 and one completel revolution to the shaft 20. A l Heretofore, the operation of removing a y coil from a reel, whereit involves the successive actuation's. of two different members,

namely, one to free the coil and the other to push' the freed coil away, has required separate actuators for said members,-a condi# tion which imposes a heavy 'burden of responsibility on the operatorin securing the properly-timed actuations of the parts. For example, in' the well-known arrangement of the Mcllvried Patent No. 452,889, of May 26, 1891, where a fluid pressure piston and cylinder unit is employedfor the actuation of the coil freeing member, and another separate piston and cylinder unit is employed for the actuation' of the coil-.pushing member, the operator is required, after completion of each coil, to perform four separate acts, in properly-timed relation, viz, (1)., to admit pressure fluid to the first unit, for the actuation of the coil-freeing member; (2), after lapse of a proper interval, to admit pressure fluid to the second unit, for the actuationv of the pusher; (3)to admit pressure fluid for the reversal of the second unit, to carry the pusher back out of the wav of the coil-freeing memreversal of the rst unit, to return the coilfreeing member to normal position.

According to my invention however, which provides a single actuator, common to both the coil-freeing and the coll-pushing members, the operator is entirely relieved of all responsibility; all that he has to do, after the completion of each coil on the reel, is to inaugurate the rotation of shaft 15 by clutching it to a motor or the like, not shown, which procures, as previously stated, a single complete revolution of the shaft 2O and the stops.
